THlLL-COUPLING.

SPECIFICATION forming part of Letters Patent No. 276,120, dated April 1'7, 1883.

Applicationliled October 31, 1882. (No model.)Y

. To all whom it may concern:

Be it known that we, ROMANUS T. WOLIS- TON and SILAS W. PRINTZ, of Bonanza, county of Sagnache, State of Colorado, haveinvented a new and useful Improvement in Thill-Gouplings, of which the following is a specification.'

ln the accompanying drawings, Figures l and 2 are perspective views of a thill-coupling of our invention. Fig. 3 is a transverse sectional elevation ot' the same. Fig. 4 is a perspective view ot' one-half of the rubber envelope that covers the hinge portion of the thilliron; and Fig. 5 is a longitudinal sectional elevation taken through line ce b of Fig. 3.

The present invention consistsvin a thillcoupling provided with a T-shaped thill-iron having a rubber-enveloped joint, upon which the'shalt of a vehicle may oscillate for a limited distance by means ot' an aperture in the cylindrical casing ot' said joint, entirely free from noise.

lt further consists in combinations and arrangements of parts whereby the aforesaid noiseless movement is practically accomplished.

ln the drawings letters of like character represent corresponding parts in each ot the iigures.

In order'that others skilled'in the art to which our invention belongs may make and use the same, we will proceed to describe its construction and operation.

Two cylindrical casings, c, are attached to the customary axle, d, of a vehicle through the agency of clips c, that extend around the aforesaid aXle in the manner shown, and then terminate in threaded ends, that pass through perforations in the horizontal extensions f of the cylindrical casings c, where they are secured by nuts in the usual manner.

Each thill-iron gis provided with a joint, h, that we completely envelop with a rubber jacket, t' t. Thisjacket is preferably made in two parts for convenience of construction, and each halt' is vprovided with a slot, j, that lits over the thill-iron g in a manner suitable for the complete covering of its joint h. The joint h, after being properly jacketed, is inserted endwise into the cylindrical casing c, the slot k in said casingforming a passage-way to permit of this being done. This slotjextends into the aforesaid casing to make connection with an aperture, l, in which the thill-iron g has a vertical oscillatory motion. After the thilliron g is inserted into the cylindrical casing c, a nut, m, is fitted over the threaded end of said casing and retains it in place. The nut mis provided with a tapering projection, n,

, that en ters the bore of the casing c, and through the agency of the slot 7c expands the casing outwardly until the nut m is completely locked.

It is obvious that the rubber casing it' may be made in more than two parts Without departing from the spirit of this invention; also that the projection n on the nut m could be dispensed with and yet made to answer the purpose for which this was intended.

In case of the wearing of the rubber jacket a liner of any kind may be put into the casing c at either end, and thus compensate for the wear by the pressure of the nutagainst said liner rubber jacket, causing the expansion of the whole jacket to the filling of its cylindrical casing.

We have represented the rubber jacket as perforated ecccntrically for the reception of the joint h. cess of rubber in front ot' the thill-iron joint. We do not wish to be conined to the precise shape ot' the thill-iron joint, as a ball-joint may be used in place of a T-join t.

Having thus described our invention, what we claim as new, and desire to secure by'Letters Patent, isv l. A thill'coupling consisting of a T-shaped thilliron, forming a joint upon which the shafts of avehicle may oscillaie, and having saidjoint completely enveloped in a rubber jacket, a cylindrical casing suitably apertured for the reception and limited movement of the aforesaid thill iron and joint, and a nut fitting over and screwing on the end of said casing for the proper confinement ot' said rubber-enveloped joint.

This we do so as to place an exc 2. A thill-coupling consisting of a thill-iron,

forming ajoint upon which the shafts of a vehicle may oscillate, and having said joint completely enveloped with rubber, a cylindrical casin g suitably apertured for the reception and limited movement of said thill iron and IOC joint, and a nut having a tapering projection that ts into the aforesaid a-pertured cylinder and expands it until securely locked.

3. In a thi11-ccupling,a slotted casing l'or 5 the reception of a chill-iron, h g, in combinacoveriug of the thill-iron joint h, substantially [a as and for the purpose specified.

In testimony whereof we have hereunto set our hands this 27th day of October, 1882.
